Apple has released the Mac mini EFI Firmware Update 1.7 via their Software Update Utility and website for direct download. According to the company, this update addresses HDMI video flicker issues on Mac mini (Late 2012) computers and is recommended for all users. It should also be noted that it updates the EFI firmware on your Mac mini to 0106.03. The Mac mini EFI Firmware Update 1.7 weighs in at 4.53 MB and requires OS X 10.8 or later.

Great news indeed! I can't wait to get home from work and get it installed. I think this bug was the only thing holding back the Mac mini from being perfect. I also feel safer recommending it to friends and family now.

There were also some issues being reported about washed out looking colors. Any news if this update corrects that as well? I've been holding off upgrading because of the HDMI issues being reported. I really want one bad for Logic, PS and Aperture though.

This update worked for me. I no longer have flickering or going to black every couple hours. I also seem to have better color saturation than before. So thanks for restoring my faith Apple! The Mac mini is once again an excellent product.

Does the improved colors survive after waking up your Mini from sleep? I've heard others complain about this. There's hope that the color problem will be solved with the Mac OS X 10.8.3 update.

Yes. I would say there is still a little room for improvement though. Which may come with the 10.8.3 update like you are saying. But mine is pretty darn good man. Especially with adjustments in Displays and on my TV through the picture controls.
